Do you require your husband/wife to always ask your permission every time he goes out with friends esp when an ex-gf is in that circle too?

Asking permission or informing is a sign of RESPECT and which lead us to have LESSER CONFLICTS. So ya, it's good to have transparency.

As long as we are aware of who we are going out with we're both ok. Have come to a point where this is something we trust each other with

I wouldn't require it, but I am hoping he will take the initiative of informing me as a sign of respect and transparency.

Yes. Because i'm his wife and should know his whereabouts. Also, for peace of mind.

thanks

For the sake of transparency, Yes I would say.

Yes its good to tell him and trust is needed
